Amiga OS predates Windows, Linux and Mac OS.  Mabye it is they that are
broken?

Is VMS broken as well for using strange paths?  Or Mac OS <= 9?

The fact is that some operating systems are different.  Now does anyone have
any suggestions about how to support this case genrically?  Is there a
reason why we can't just change the "./" to "" in this case?
